Anatoli Mikhailovich Granovsky was a NKVD agent who defected to the West in 1946 and authored an autobiographical book about his career in Soviet intelligence. Granovsky was the son of a high-ranking Soviet bureaucrat, Mikhail Granovsky, who was a victim of the Stalinist Purges of the late 1930s. To find his father in the Soviet Gulag system, Granovsky allowed himself to be arrested by the NKVD on false charges and interred in the same penal system. As a result of his past friendships with the children of his father's high-ranking former colleagues, Granovsky was recruited as an NKVD agent to spy on those same acquaintances in July 1939. After defecting to Sweden in autumn 1946, Granovsky wrote the book I Was an NKVD Agent.
